BIRMINGHAM, Alabama -- Six months after a fatal flight information sign collapse at Birmingham-Shuttlesworth International Airport, there isn't any word on whether the incident led to any design changes or if the removed displays will be replaced.

The display -- technically known as a multi-user flight information display, or MUFID -- toppled March 22, killing 10-year-old Luke Bresette and seriously injuring his mother and two younger brothers.

The Bresettes were traveling back home to the Kansas City area after a Spring Break trip to Florida.

The freestanding display which collapsed was removed after the collapse, and another was removed the following day. The two remaining floor-based displays were removed April 2 after airport officials said they learned contractors expressed "serious concerns" about the safety of the signs prior to the collapse.
